Carrying a TiAlN PVD coating under the WK40RC material grade designation, this single-end tool delivers both roughing and finishing capability in one geometry. The 4-flute configuration features a variable helix and right-hand cutting direction to reduce chatter and improve chip evacuation. With an 8.00mm mill diameter and a 0.50mm corner radius, it is built for precise contouring and edge integrity in production environments. Machinists and tooling technicians working with CNC machining centers are the primary installers of this head.\u003c\/p\u003e\n\u003cp\u003eThis end mill head is designed for stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. The extended reach geometry, with a 27.00mm reach length and 19.00mm length of cut, makes it well suited for deep-pocket milling and long-reach applications where a standard-length tool cannot access the feature. The straight-cylindrical shank with an 8.00mm diameter and h5 tolerance is compatible with precision toolholders used in CNC milling operations. The normal pitch and center-cutting capability round out its application range for both slotting and peripheral milling passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating (WK40RC grade) for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable helix flute geometry reduces vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 27.00mm reach length for deep-pocket and long-reach applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, supporting both plunge entry and peripheral milling\u003c\/li\u003e\n  \u003cli\u003eRoughing and finishing material removal in a single tool for stainless steel and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with precision CNC toolholders accepting an 8.00mm straight-cylindrical shank.

Ensure the toolholder bore and retention mechanism are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping before initiating a cut. Always reference the manufacturer cutting data recommendations for feed rate, spindle speed, and depth of cut specific to the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 8.00mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 19.00mm (2.5000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.50mm (0.0390 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 27.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD, WK40RC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extended\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MC251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.104 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.54 inches x 0.71 inches x 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-PROTOTYP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6814326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67918829093170,"sku":"6814326","price":176.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df3633bd7cd1c3dae5736f37ad514091_5c3abf1d-be82-422b-929a-67229e6f63ca.jpg?v=1791273469","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6814326-corner-radius-end-mill-4-flute-8mm","provider":"Voomi Supply","version":"1.0","type":"link"}
